Xiong Jinping, a professor at the School of Materials Science and Engineering at Beijing University of Chemical Technology, pointed out: Although the stainless steel electric kettle contains manganese, it is difficult to dissolve during the process of boiling water . Even if it is continuously boiled repeatedly for more than 1,000 hours , the precipitated manganese is in ionic form , has little impact on the human body, and has no risk of cancer .

The national standard for tap water in China is that the total hardness does not exceed 450 mg . Even if you drink two liters of hardness per day, Water will not exceed the calcium limit.
